To all whom it may concern:

Be it known that I, FRANK Mosssnno, a

citizen of the United States, residing at Attleboro, in the county of Bristol'and State of l have invented certain new and useful Improvements in Reels, of which the following is a specification.

My invention relates to spools or reels of. large size, such as are used for carrying wire, lead-covered telephone cables and the like, and which consequently, require to be very strong and solidly constructed, in order to support th heavy loads and withstand the rough usag I to which they are subjected.

Heretofore, reels for the described, and other similar urposes, have been constructed so far as am aware, either wholly of wood, or partly of wood and partly of cast iron. Such reels are necessarily very heavy and consequently clumsy, and do not prove satisfactory in ractice.

The object o my invention is to improve the construction of reels of the class described by making the heads, which are necessarily of large diameter and must be capable of supporting a great weight, out of sheetmetal, which is pressed into shape to admit of ready and secure attachment of the hub to had to the accompanying drawings, in which,

tions, and Fig. 5 is an end view of the hub of tially; Said heads plate, pressed into shap sole same; fthird, trunnions secured axiall *of the I the heads, and to impart great rigidity and stifl'ness to the latter as well as to the whole I structure. The heads are also providcdwith means whereby the reel may be mounted on bearings-so that it can be rotated, as for instance, while the wire or cable is being wound onto, or unwound from the reel.

The construction of my improved reel will now be described in detail, reference being Figure 1 is an axial section of one end of the hub of my improved reel; Fig. 2 is an end view of the same; Figs. 3 and 4 are views similar to Fig. l but showing modifica- Fig. 4.

The essential elements of my improved reel made of wood and preferably solid; second, a pair of shown in the drawings and that one only parare made from steels, with or without and my present improvement relates an esat the centre of the y to the construction heads, whereby the reel may be pivotally mounted, and, fourth, bolts for securing the parts together.

Referring to l and 2, the hub 1 con sists, as Ihave stated abevo, of a solid wooden cylinder, in the ends of which are formed circular recesses 12, for a purpose. .to bedescribed, and whichhas a cirwlarserics of holes formed therein parallel to the axis for thereception of the securing bolts '7. I will confine my description to one of the heads only, since they are exactly alike. The steel disk, from which the head made, is placed in dies and pressed, in a well-known manner, so as to form a central circular recess or depression 8 of a diameter corresponding to that of the hub 1 and in which the ends of said hub rest. At the centre of this circular recess 8 the disk has a circular aperture formed therein, the edges of which are turned out to form a flange 9. In this form of my invention the journals by which the reel is pivotally car ried are formed separately from the heads. Each of said journals consists of a closed-end hollow cylinder 10, the edges surrounding the open end of which are turned" outwardly to form a flange 11, the diameter of which corresponds to that of recess 2 in the end of the hu 1.

the central aperbolts are tightened up, the hub is securely clamped bctween'the heads, and the trunnions 10 are firmly secured by means of their flan es 1]. between the ends of the hub and the heads.

In Fig. 3 I have shown a modification of my invention in which the trunnions 12 are formed integral with the heads during the pressing operation. In this case the hub 1 does not require to have the circular recess 2 as formed in its ends, and there is, of course,

no necessity for the central apertures in the recesses S of the heads. The trunnion 12 is formed of two diameters so as to leave a shoulder 13 to bear against the end of the journal in which the reel is carried.

The outside diameter of the tubular trunnions corresponds to the inside diameter and then the without Wishing to be limited to the exact recesses fitting riveting over the In Fig. ithe modification consists in making the trunnion 1a from a solid bar of metal and securing the same in the circular apertureforrned in the recess 8 of the head 5 by inner end of the trunnions as shownat 15. The hub 1 has a circular depression formed therein to accommodate the riveted end' of the trunnion which latter has a collar bearing against the outside surface of the head.

Having thusdescribedmy invention and form and arrangement of parts shown what I claim is I 1. A reel of the classdescribed, the same "consisting of a solid cylindrical wooden hub, pressed steel heads having central circular over the ends of said hub, trunnions secured to said heads between the between the ends of the hu cent faces of the, heads, and bolts passing same and the ends of said hub and bolts passed through said heads and hub to secure.

Y the structure together.

2. A reel of the class described, consisting of a solid cylindrical Wooden hub, pressed name to this specification in the presence ofsteel heads having circular recesses fitting over the ends of said hub andeach having a central flanged aperture, a closed end tubular trunnion passed through each of said flanged apertures and having a flange on its inner end fitting in a recess formed in each end of the hub and bolts passed through said pprts together, 1

heads and hubs to secure said 3. A reel of the class 'descr ed, the same consisting of acylindrical hub, pressed-steel heads having circular recesses fitting over the ends of said hub, each of saidreces'ses having a central aperture, trunnions fitting in said apertures and having enlar ed heads lying and the adja- "being pressed outwardly to form a trunnion,

and bolts passing longitudinally through said hub and heads to secure them together.

In testimony whereof l have signed my two subscribing witnesses. p
